Vector is an important concept used in almost all physics topics learned in high school. The goal of this study is to identify the understanding of vector concepts using mathematical and physical representation in Grade X high school students in Malang (East Java, Indonesia) and Waikabubak town...
在1890年On the importance of quaternionsin physics一文中,泰特赞扬“四元数的自然特质。它以最显而易见的方式越过坐标的任意性直接解释了空间的物理特性(naturalness of quaternions which removed the arbitrariness of coordinatesand reveal the physical properties of space in themost obvious way)”。四元数是m...

In elementary math, the term "polar vector" is used to refer to a representation of a vector as a vector magnitude (length) and angle, which is equivalent to specifying its endpoints in polar coordinates (illustrated above). In physics, a polar vector is a vector such as the radius vect...
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature arevelocity, momentum, force,electromagnetic fieldsand weight. A quantity or phenomen...
